I was trying to watch some Apple ads on apple.com, but they don't load. I can, however, watch all of their guided tours and tutorials. I assume it's because the word "ad" is in there, so I added apple.com and movies.apple.com to my whitelist. However, I still can't watch the Apple ads.

can you give a link to 1 of the pages that the video isnt loading on? every video I have seen there has been hosted on apple.com (you dont need to whitelist both movies.apple.com and apple.com as apple.com covers every subdomain of apple.com)It's possible the video ads are just taking longer to load

Thanks for all the responses. And, I'm embarrassed to say, it wasn't OpenDNS. I couldn't watch the ads from work on the same laptop either. Turns out the Firefox extension Adblock Plus was blocking the ads because of the word "ad" even though it used to work before. After putting apple.com on the ABP whitelist, the ads started playing.

ABP is an extremely effective tool with a decent list/s and needs to be tuned cautiously. One white list I would recommend for anyone using it is https://* (annoying ads will be on some secure sites) or white listing the domains you visit with a secure connection. Such as: your bank, e-commerce sites.
